The rectifier ruxruxo buuxa, iyo sida ay u shaqayso

Rectifier converters koronto loo yaqaan, kuwaas oo Semiconductor ama qalab kale oo elektaroonik ah diinta xoog aqbasho AC in wax soo saarka DC. rectifier ruxruxo dhisay on a bar-buundada ama circuit buundada, dhismaha faahfaahsan oo aynu ka fiirsan doonaa.

nuxurka ka mid ah qalabka iyo rectifier ruxruxo-buuxa ah

Inta badan qalabka waxay abuurtaa danab Cabidkariin unidirectional. Si la simi pulsation, isticmaal filtarrada gaar ah.
Si loo hagaajiyo oo xuduudaheedu rectifier lagama maarmaan si ay u bixiyaan socodka hadda labada bar-waqtiyada danab talooyin ah. Ujeedada this, laba nooc oo wareeggeedii isticmaalo sixitaan nus-la ruxruxo, oo ka shaqeeyaan sidii antiphase iyo synchronism la load caadi ah.

Iyada oo ka mid noqoshada this u baahantahay laba il danab aasaasiga ah, taas oo yeelan doonaan hal dhibic ka caadiga ah. nidaamka loo yaqaan "rectifier ruxruxo buuxa dhibic dhexe." Qiimaha celcelis ahaan danab ee resistors load at sixitaan la ruxruxo-full of tilmaamayaasha sida ay u badnaan doontaa laba jeer circuit nus-la ruxruxo.

Waa in la ogaadaa in qorsheyaasha dvuhpolupeiodnoy haysashada midpoint ah, ayaa dhinacyada ay negative. Marka hadda maraa mid diode ee ugu sarreysa ka soo horjeeda dambe danab wajiga gaadho ugu badnaan laba jeer danab talooyin ah, waxa ay tahay in la xusuusto xulashada dioska- for rectifier ah.

Marka tan la eego, ka fiirsan wareeg ah rectifier ruxruxo buuxa faahfaahsan oo dheeraad ah isagoo content bir isagoo badan oo firfircoon oo u dhiganta a iska caabin ah gudaha. Tani waxay keenaysaa in joogitaanka khasaare badan oo la xidhiidha kululaynta weyn oo transformer ah.

In dhismaha circuit noocan oo kale ah isagoo capacitor yeeesha ah, waxaa lagama maarmaan ah in la tixgeliyo in danab talantaalli cabbirka had iyo jeer waa in qiimaha qalliinka, kuwaas oo si weyn u yar yahay Ilodanimada inayan ugu badan. Maqnaanshaha load on capacitor ee danab ku hagaajin had iyo jeer waa Ilodanimada siman. Taas macnaheedu waa in rectifier ruxruxo-buuxa ah isagoo ah hal waji talantaalli hadda capacitor 12, marka load ma aqbalo danab a of 17 V. Laga soo bilaabo tan, waxaannu ku tirinnaa karaa in ka yar load danab ku hagaajin hoos, laakiin ma noqon in ka yar danab ku doorsoomayaasha jira hadda iyo waxaa go'aamin doona awoodda capacitor yeeesha ah.

circuit rectifier noocan oo kale ah waxaa lagu tilmaamay sida soo socota. Si loo xakameeyo faragelinta ee aasaasiga ah transformer ku fuuli jiray waa xiran filter a, taasoo ka kooban yahay laba capacitors dhibic ku lifaaqan dhexe dhinaca dhulka ah. Waxaa loo baahan yahay in ay unipolar, iyo si loo yareeyo itimaalka burburka ka mid ah danab ku qiimeeyo iyaga at waa 200 V.

Sida caadiga ah, is beddel ayaa lagu wadaa in condenser ah, waxaa lagama maarmaan ah in ay is hortaagaan danab dhaxe ee lagu jiro hawlgalka ee capacitors rectifier ah. transformer rectifier Fullwave ayaa sare ah loogu fuuli jiray la tuubada xarun, laakiin in this buundada saarka circuit muhiim ma aha. Filter ee rectifier iyo capacitor waa laba resistor taxane. Si kastaba ha ahaatee, heerka hoose ee Cabidkariin la aqbali karo in aad ku darto capacitor wax soo saarka kale oo resistor.

Tan iyo mashiinada korontada ku shaqeeyaan si waafaqsan mabda'a ytimaada, rectifiers danab wada jir ah ula inverter ku jira laba nooc oo makiinadaha korontada. qalab inverter yeedhay badasha danab DC si AC.
